STICK-PIN RETAINER.

Specification of Letters Patent.

To ,w21-Z whom it may concern:

Be it known that I, ROBERT CORN, a citizen ofthe United States, and a resident of the city .of New York, boron Vh of Manhattan, in the county and State of ew York, have invented' a new and Improved Stick-Pin Retainer, of which the following is a full, clear, and exact description;

The purpose of the invention is to provide a device especially adapted for use in connection with stick-pins, being removably applied to the pin after the pin has been passed through the scarf or tie or similar article to prevent withdrawal of the pin without the wearers knowledge, the device being concealed when worn.

A further purpose of the invention is to so construct a stick-pin retainer that it will be com act, exceedingly simple and economic, not` iable to et out of order, and so that spring-control ed friction-rollers contained within the easing will have an uninterrupted maxirnurnbearing against both the inserted pin and opposing portions of the casing while the parts' are in normal position, which rollers also have increasedbearinw on the pin and casing in'proportion to the effort expended to forcibly withdraw thepin.

Another purpose of the invention is to provide means whereby the rollers are the only Therefore they can be, made of such dimensions as to obtain the greatest possible frictional surface in a necessarily small device. The construction is also'such that the pin can be released from the device by the wearer at any time and with ease and despatch.

The invention consist-s in the novel construction' and combination of the several parts, as -will be hereinafter fully s'et forth, and pointed out in` the claim.

Reference is to be had to the accompanying drawings, forming a part oftliis specifica-- tion, in which similar characters of reference indicate corresponding parts in all the figures. Figure 1 is a perspective view of the device inposition upon a pin. Fig. 2 is a vertical section taken practically on the line 2 2 of Fig` 1. F ig. 3 is a vertical section takensubstantially on the line 3 3 of Fig. 1. Fig. 4 is a side elevation of the pin-receivin section of 'the device. Fig. 5 is a vertica section Ik`tlirough a device dille-ring in some articulars 'from the construction shown in t ie other views. Fig. G is a horizontal sectiontaken practically on the line 6 6 of Fig. 5; and Fig. 7

isa vertical section through a portion of the d evice, illustratingV another slight modification in construction. i

A represents the body of theV device, which is hollow and is rectangular in cross-section;

but opposing sides 10 and 1 1 ofthe device are inwardly curved from a point near their cen-- ters to their upper ends, forming thereb u pper inner curved faces 12 and 13 at suc sides, as islparticularly shown in' Figs. 1, 2,

and 3... The top of the bodycasing -A is4 ti'on B is below the upper open end of the body-casing A, and its lower ortion extends below the bottom'plate 14 t )rough the saidl opening 15 therein and terminates in an enlargement or vknob 16, whereby the said tubular pin-receiving section may be drawn downward a certain distancefrom within the casing. The bore of the said pin-receiving section 4B extends through from end to end and is of such diameter as to loosely receive he stick-pin C, as is especially shownin t(in opposite sides of the pin-receiving section B, near the t'op,-opposing coi'icav'edreN cesse's 17 are made, and these recesses 17 face the inclined surfaces 12 and 13 at the upper portion of the box-easing, as-is shown in Figs-Zand 5. Each of the said recesses 17 loosely receives a friction-roller' 1S, and these rollers, by reason of the recesses 17, ex-

tencl into the bore of the pin-receiving'sec-l tion B and likewise engage witli'the inclined or curved surfaces 12 and 13 of the easing. These rollers are further supported by' a ilange or collar 1) L on the iii-carrying se'ction B, and the flange or col ar is engaged by a spring 19, loosely coiled around the pincalrying sccti on B and having bearing .at its lower end on the bottoni plate 14 of the casing. The spring 19, acting against the col` lar 19, tends to carry the pin-carrying section upward to such an extent as to obtain the necessary frictional engagement between the rollers and the inclined faces orsurfaces of the body-casing and between the rollers and thepin(whcu passed downward through the said receiving-section B. therefore, no need to engage with tliepin-carrying. section'at any point in its length, .having needl only to bearagainst the' collar. `The friction-rollers 18 are of sufficient lengthto extend practically from one straight side of 3 the body-casing to the other, as is shown in Fig. 3., Bythis arrangement it will vbe observed: that" the rollers may be mad'e quite' large-in-diaixite'r in proportion to thcsize of the'casin'gfso ,as to obtain a maximum fricro tipnal engagement' withthe pin and the easing. Itfls i'glfit'her evident by reference to' A2jthat after'thepinis in position in. the 'pincarying tube an eilert to withdraw, the pin therefrom from above will tend to cause i 5 thel-frietiomrollers to bind the pin and the casingzall the tighter. It is furthermore evident that whenit isdesired to remove the de- -1 vice from the pin it lis simply necessary to Pull the pinfreeeivingf section B downward.V

zo permitting vthex'rollers to l rolll down their in- 'olined planes Orth@ inclined surfaces 12 and 13 of'theeasin'g to the wider portion thereof, y

whereupon. the rollers maybe se arated when the pin is moved out from the eviee.' i`- In Figs. 5 and 6' I have illustrated a slight Inodiiicatio'n orA alshght'departure' in con# struetion from the construction above de- "scribed tothe extent that thepin-reoeiving tube Bris ofuniform diameter .from end toA 39. end, andbelow-the 'bottom llliof the bo'dy- I casing A a flat preferably reot-angularlplate" 2() is'l secured to the said pin-receiving section.

'ortube,'a'nd the said plate is provided with end V'lugs 21. The-body oi' the plate is re' bottom of tlie`body-oasing A and is soldered or otherwise attached thereto.' In this form o1 the devioe when it is desired to release the pin from binding engagement with the friction-rollers `18 the pin-receivingr tube is drawn down by pressing in the same direction -on the lugs 21 ofthe slide-plate 20.

'lhe form of the device shown in Fig. 7 is practically the' same as that illustrated in Fig. 5, except that. the box-easing 22 is omitted and opposite sides of the easing are elongated to provide guides for the plate 20, leaving the other'sides open for the free pas,- sage of the lugs 21.. f

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- A stick-pin retainer, having the oppositeside walls thereof .converging toward the top of the easing, a tubular pin-receiving section section 4having' oppositely-a-rranged- -openings in the walls thereof above the collar, a spring between the collarI and the bottom of the easing andnormally retaining the pin-receiving section in its uppermost position, rollers in the opposite openings engaging the converging Walls whereby to force'said 'rollers '11iwardly to grip the pin when the pinfreceiving sec-tion is moved upward by lthe spring, said pin-receiving section having means oonneoted J therewith, and extendingoutsidc of the casing, whereby to move .said section against the resistance of the spring.

'In testimony whereof I have signed my name to this specification in the presence of two subscribingwitnesses.
